Taking RAVICTI By Mouth

  • Read transcript

    Welcome to the RAVICTI (glycerol phenylbutyrate) Oral Liquid instructional dosing video.

    In this video you will see step-by-step instructions for the oral administration of RAVICTI for you or your child.

    This video is intended to complement the instructions you have already received from your doctor. Always take RAVICTI exactly as directed by your doctor.

    Do not mix RAVICTI with formula or any other liquids.

    Now, let’s get started.

    Your RAVICTI shipment includes

    a 25-milliliter bottle of RAVICTI, a reclosable bottle cap adapter, and an oral syringe.

    When dosing RAVICTI, be sure to use the oral syringe provided with the product.

    First, remove the childproof cap on the RAVICTI bottle. To do that, push down on the cap while twisting it to the left.

    Then, attach the reclosable bottle cap adapter onto the bottle. Put it on top of the bottle and twist it to the right.

    Make sure it is secured tightly on the bottle.

    While holding the RAVICTI bottle securely, place the tip of the oral syringe into the reclosable bottle cap adapter.

    Turn the bottle upside down with the oral syringe still inserted.

    Now you’re ready to fill the oral syringe with RAVICTI.

    Withdraw the prescribed dose of RAVICTI with the dry oral syringe by pulling the plunger back.

    Pull the plunger back until the first line of the black rubber stopper is even with the dosing mark. The dosing marks are on the barrel of the oral syringe. Match the dosing mark with the amount of medicine prescribed by your doctor.

    Then, turn the bottle upright again.

    If there are large air bubbles, push the medicine back into the bottle. Do this slowly.

    Then draw up the medicine again.

    Once you have your oral syringe ready, place it into the mouth. Push the plunger to squirt the medicine directly into the mouth.

    Make sure all of the medicine is pushed out of the oral syringe and swallowed.

    Put the cap on the oral syringe.

    Drink liquid or eat some food right after taking RAVICTI.

    This helps ensure that all of the medicine is swallowed.

    Close the tab on the reclosable bottle cap adapter.

    Make sure it’s closed tightly.

    After the last dose of the day, dispose of the oral syringe.

    Take the exact amount of RAVICTI Oral Liquid as instructed by your doctor.

    Your doctor may change your dose if needed.

    Take RAVICTI with food or formula.

    In an infant who is breastfeeding, give RAVICTI just prior to breastfeeding.

    Use a new reclosable bottle cap adapter with each new bottle of RAVICTI that is opened.

    Use a new dry oral syringe to withdraw each prescribed dose of RAVICTI.

    If you take too much RAVICTI, call your doctor or the Poison Control Center at 1-800-222-1222 or go to the nearest hospital emergency room right away.

    Do not stop taking RAVICTI unless your doctor tells you to stop.

    If you miss a dose of RAVICTI, take it as soon as possible.

    Do not take 2 doses of RAVICTI at the same time.

    If you miss more than 1 dose and are not feeling well, call your doctor or nurse right away.

    If you still have questions about how to take RAVICTI with an oral syringe, please contact your doctor for more information.

    If RAVICTI is in contact with water, it will become cloudy in appearance. If the contents are in contact with water or cloudy, then do not use the remaining RAVICTI and contact your prescribing doctor or pharmacy.

    Discard bottle and any remaining contents 28 days after opening.

    Ask your pharmacist for oral syringes and a reclosable bottle cap adapter for each bottle you receive if you do not have them.

Taking RAVICTI By Feeding Tube

  • Read transcript

    Welcome to the RAVICTI (glycerol phenylbutyrate) Oral Liquid instructional dosing video.

    In this video, you will see step-by-step instructions for administration of RAVICTI if you or your child have a nasogastric or gastrostomy feeding tube.

    If you can swallow liquids, it is recommended you take RAVICTI by mouth.

    This video is intended to complement the instructions you have already received from your doctor. Always take RAVICTI exactly as directed by your doctor.

    Do not mix RAVICTI with formula or any other liquids.

    Now, let’s get started.

    Your RAVICTI shipment includes:

    a 25-milliliter bottle of RAVICTI, a reclosable bottle cap adapter, and an oral syringe.

    When dosing RAVICTI, be sure to use a new dry oral syringe.

    First, remove the childproof cap on the RAVICTI bottle. To do that, push down on the cap while twisting it to the left.

    Then, attach the reclosable bottle cap adapter onto the bottle. Put it on top of the bottle and twist it to the right.

    Make sure it is secured tightly on the bottle.

    While holding the RAVICTI bottle securely, place the tip of the oral syringe into the reclosable bottle cap adapter.

    Turn the bottle upside down with the oral syringe still inserted.

    Now you’re ready to fill the oral syringe with RAVICTI.

    Withdraw the prescribed dose of RAVICTI with the dry oral syringe by pulling the plunger back.

    Pull the plunger back until the first line of the black rubber stopper is even with the dosing mark. The dosing marks are on the barrel of the oral dosing syringe. Match the dosing mark with the amount of medicine prescribed by your doctor.

    Then, turn the bottle upright again.

    If there are large air bubbles, push the medicine back into the bottle. Do this slowly.

    Then draw up the medicine again.

    Next, place the tip of the oral syringe into the smaller port of the feeding tube.

    The smaller port of the nasogastric or gastrostomy feeding tube is used for medicine.

    Ask your doctor if you are not sure which port to use.

    Using the plunger of the oral dosing syringe, slowly and carefully push RAVICTI into the feeding tube.

    Make sure all of the medicine is pushed out of the oral dosing syringe.

    After you have pushed all of the RAVICTI into the feeding tube, remove the oral syringe, put the cap on the oral syringe, and set it aside.

    Close the tab on the reclosable bottle cap adapter.

    Make sure it’s closed tightly.

    Use a separate large syringe to flush water into the feeding tube. A large syringe can be found in the box containing your feeding tube.

    Make sure all of the water or formula drains through the feeding tube.

    For patients who have a nasogastric tube or gastrostomy tube in place, give RAVICTI as follows:

    • Use an oral syringe to withdraw the prescribed dosage of RAVICTI from the bottle.
    • Place the tip of the syringe into the tip of the gastrostomy/nasogastric tube.
    • Using the plunger of the syringe, push RAVICTI into the tube.
    • Flush once with 10 mL of water or formula and allow the flush to drain.
    • If needed, flush a second time with an additional 10 mL of water or formula to clear the tube.

    You can use 1 oral syringe and 1 reclosable bottle cap adapter for all doses each day.

    You can also choose to use a new oral syringe with each dose.

    Do not rinse the reclosable bottle cap adapter or oral syringe between doses.

    After the last dose of the day, dispose of the oral syringe.

    Take the exact amount of RAVICTI Oral Liquid as instructed by your doctor.

    Your doctor may change your dose if needed.

    Take RAVICTI with food or formula.

    In an infant who is breastfeeding, give RAVICTI just prior to breastfeeding.

    Use a new reclosable bottle cap adapter with each new bottle of RAVICTI that is opened.

    Use a new dry oral syringe to withdraw each prescribed dose of RAVICTI.

    If you take too much RAVICTI, call your doctor or the Poison Control Center at 1-800-222-1222 or go to the nearest hospital emergency room right away.

    Do not stop taking RAVICTI unless your doctor tells you to stop.

    If you miss a dose of RAVICTI, take it as soon as possible.

    Do not take 2 doses of RAVICTI at the same time.

    If you miss more than 1 dose and are not feeling well, call your doctor or nurse right away.

    If you still have questions about how to take RAVICTI with an oral syringe, please contact your doctor for more information.

    1. For patients who require a volume of less than 1 mL per dose via nasogastric or gastrostomy tube, the delivered dosage may be less than anticipated due to adherence of RAVICTI to the plastic tubing. Therefore, these patients should be closely monitored using ammonia levels following initiation of RAVICTI dosing or dosage adjustments.

    If RAVICTI is in contact with water, it will become cloudy in appearance.

    If the contents are in contact with water or cloudy, then do not use the remaining RAVICTI and contact your prescribing doctor or pharmacy.

    Discard bottle and any remaining contents 28 days after opening.

    Ask your pharmacist for oral syringes and a reclosable bottle cap adapter for each bottle you receive if you do not have them.

How RAVICTI Works:

  • Read transcript

    Hello, today I want to talk to you about Understanding Urea Cycle Disorders and Your RAVICTI Treatment. First, let's talk about Urea Cycle Disorders. What is a Urea Cycle Disorder?

    A urea cycle disorder, or UCD, is a rare inherited condition where toxic levels of waste called ammonia build up in the blood and cause damage throughout the body.

    Ammonia is released when the body digests protein from food.

    Normally, the liver makes enzymes that break down the ammonia into urea. The body then gets rid of urea through urine.

    In people with a UCD, these enzymes don’t work right, so ammonia builds up in the blood.

    High levels of ammonia in the blood can make you very sick and cause serious health problems. A low-protein diet and supplements can help keep ammonia levels down, but sometimes this isn’t enough.

    Adding Ravicti can help keep ammonia at a safe level in the blood.

    Ravicti is slowly broken down by a naturally-occurring enzyme found in the digestive tract.

    Ravicti passes through the stomach and starts to slowly break down in the intestine. Once it breaks down, it can start getting to work.

    A part of Ravicti then binds to ammonia molecules to form a Ravicti/ammonia complex that is excreted in the urine.

    When taken correctly, Ravicti works to keep removing extra ammonia throughout the entire day. RAVICTI may cause side effects. The most common side effects of RAVICTI in adults include: diarrhea, gas, headache, abdomen (stomach) pain, vomiting, tiredness, decreased appetite, indigestion or heartburn.

    So how do you take Ravicti? Ravicti is a liquid that you take by mouth with a syringe or dosing cup 3 or more times a day with a low-protein diet and in some cases dietary supplements.

    It’s important to take Ravicti exactly as your doctor tells you in order to keep the ammonia in your body at a safe level.
    Set reminders so you don’t forget to take your dose ........ and keep track of when you do take it.

    A UCD is a lifelong disease that can cause organ damage and other very serious health problems over time without proper treatment. So even if you’re feeling fine, it’s important to continue taking your Ravicti to help prevent toxic buildup of ammonia in the blood. Talk to your doctor for more information and to help create a routine that works for you.

    JESS: We have three beautiful girls. Lucy, who’s 9, Emmy, who’s 6, and Alice, who’s 3. And our little Emmy has a urea cycle disorder.

    It definitely impacts all of us, not just Emmy or just Mike and I. Lucy has had the biggest impact out of all of the girls. She went from having all the attention and it just being her, to having a sister with special needs that she had to share a lot of attention with.

    She has stepped up and is a nurturer and she takes care of Emmy. She makes sure that she gets where she needs to be. That she has friends. She watches out for her everywhere we go. Every day when I pick ‘em up from school, she’s holding her hand and walking her to the car.

    JESS: You can’t do this by yourself. You need a team. It takes a…

    MIKE: A village.

    JESS: A village to raise any child. But definitely in a situation where you have a child with special needs, you have to have help.

    We have a lot of RAVictories with Emmy. Any time she learns something new, makes my Mama heart so proud just to watch her succeed at something.

    When she hits her 15 grams of protein in a day. Drinks all of her milk in the same day.

    With her protein goals, we’ve always struggled to get her to eat. So, any time that we hit her protein goal, it’s a RAVictory. It’s something to celebrate each day.

    My RAVictory for us, for me at least, is Emmy telling me she loves me. She didn’t always used to do that. And now she tells me she misses me. I took a business trip for work. Was gone for 3 days. And it’s like I was gone for a month and she couldn’t wait to tell me how much she missed me. That’s definitely a RAVictory in my book.

    Each time that she hits a milestone or something, she’s beating expectations. So, it’s amazing to us and makes us excited. And so her starting school this year, she’s been making friends and kids are wanting her to come and play at their houses. And it just makes me so happy.

    Something that I hope for Emmy, she recently has started a dance class. And she really loves it. And it’s so great to watch her dance, ‘cause she has the biggest smile on her face. She really loves it so much.

    David: Before RAVICTI the medicine they were taking was burdensome. I could not leave our house without a backpack. And that backpack, it had the medicine in it, but it also had everything I needed to prepare the medicine.

    It formed our life. Everywhere we went, we’re connected to the medicine. And it took a lot of time to prepare, and you had to measure and mix and there was so much of that.

    So my life wasn’t revolving around what we were doing. Everything we did revolved around taking medicine.

    Isaac: My mom was taking the pills. I was taking the powder. It took me about 15 minutes per day just to take one round of medicine.

    Patricia: The other medication, involved swallowing up to 39 pills a day. And I’m at work, and I’m in front of my students or my coworkers trying to down all these pills with my lunch.

    I know RAVICTI is not always going to work for everybody. But for myself my ammonia levels are well maintained.

    David: Not everyone is this way. But for us, RAVICTI made a huge difference. They simply measure it and they take it right there on the spot, and we move forward.

Emily

  • Read transcript

    Hanging out with friends is my RAVictory because my friends are a big part of my life and I feel very happy when I get to spend time with them.

    To manage my ammonia levels, I eat low-protein diets and I take my vitamins and medicine.

    I take RAVICTI three times a day, after breakfast, after lunch and after dinner. And I take it with a cup of juice or water.

    She doesn’t worry about having to be refrigerated and the RAVICTI comes in a small bottle. She carries it when we have to go out for the day.

    What motivates me to achieve my RAVictories and keep my ammonia levels low is that I don’t want to have my family see me in the hospital.

    Emily’s RAVictory would be taking her medicine. Just being a teenager. You know, doing sports.

    Playing her flute. Doing personal things that she wants to do. And for me, that’s her RAVictory.

    When I think of Emily, I think of someone really strong, beautiful, inside and out. Someone very sincere and brave. And I don’t know what I’d do without you.

    When I look to the future, the RAVictories I hope to achieve are going to college, traveling to Hawaii, and cooking more low-protein meals.

    I gave birth to a perfect little baby boy. When he was two days old, he started getting very sick and having symptoms of having a UCD.

    We were able to get a diagnosis and I was able to get tested. And I found out that I actually am a carrier of the genetic disorder. When I got pregnant with my second child, I was very scared. It was a very, very hard decision and at 11, 12 weeks, I found out that my baby tested positive for this same genetic disorder that my son had.

    Fortunately, because we had that diagnosis, we were able to have a plan of action for bringing Myiah into the world

    When I was first diagnosed with a urea cycle disorder, I was not put on any medication. It wasn’t until after I had my first daughter, about five or six years later. I was experiencing really bad headaches and I have always struggled to gain weight. My whole life I was like 90 some pounds. It was very difficult for me

    When I started experiencing more symptoms, as I was getting older, my doctors put me on sodium phenylbutyrate. It tasted terrible. It was very difficult for me to mask the flavor at all. I did not want to take my medicine.

    When she was born, she needed to be placed on medication due to her severity of her genetic disorder, so they started her on sodium phenylbutyrate and she took it orally.

    Luckily, Myiah, she tolerated the medicine until she was about two years old, and that’s when we were lucky enough that RAVICTI was approved for two years and up

    My decision to start taking RAVICTI was first approached to me, for myself, actually, by my doctor. She brought it up to me. I knew about it because I had connected with multiple other parents that either themselves or they had a child that was either in the study for the RAVICTI or was actually taking it. I knew it was definitely something that I was interested in looking into.

    Starting RAVICTI was a little difficult. I had to previously be prescribed the sodium phenylbutyrate to see how that medication worked for me first. It was awful to take. I wanted to throw up.

    My insurance, they will require a prior authorization for the RAVICTI. If you have trouble getting coverage for the RAVICTI, there’s so many options out there.

    Myiah was put on it as soon as it was approved for children her age. We started the process of getting her prior authorization approved for her to take RAVICTI and she’s been taking it ever since.

    She’s done amazing on it and there was no issues with her getting coverage.

    I take RAVICTI three times a day. Myiah, she’s able to take it two times a day rather than three. We take it once in the morning when we wake up and I take a dose with me to work. I put it in the syringe that it comes with, and I pack it in a little baggie and since I don’t need to mix it with anything, I can just take it and then I usually just take a sip of water afterwards. And then our evening doses are before bed.

    Molly: I love being outdoors. I think it just stems from having so much energy as a kid and not being able to stand still, always needing to go-go-go. Go to a playground. Go do this. Get your energy out. And I just have learned to appreciate all of the nature that is in Washington State.

    My name is Molly. I am 23. And I was diagnosed with a UCD when I was 3-and-a-half.

    It was just something I kind of always knew that I had, and I think it was more of a revelation to realize that not everybody grew up the way that I grew up. Not everybody grew up taking X amount of medications or had to go to the doctor X amount of times, I think that was more impactful realizing, because I had always lived this way.

    To see and feel like I looked different was more something to cope with. I was never a person to worry about taking meds in front of people. I never really hid it.

    Managing my UCD with friends and being social can be difficult at times. There are meals that I can’t eat

    I’ve found that if I figure out what I’m doing food-wise before, if I look at menus, if I go online. I’m able to figure out what I can do, what I need, before I actually am put in that situation.

    Every week, I like to do things very similar. I like routine. My favorite thing to do with Grant, my boyfriend, is go down to the beach and walk around, as well as get froyo beforehand.

    My passion for animals has always existed. I want to continue going to school in veterinary medicine and work with large and exotic animals. We’re at the Woodland Park

    Zoo. My favorite part was going and getting to see the bear play in the water. Working with animals brings me joy because it’s a comfort that I get that I can’t really get anywhere else. It’s eases anxiety and just makes me feel like I am able to help and that, to me, feels so important.

    Allison: It was difficult for her to interact with peers when she was younger and she started gravitating towards animals. They were, they were loving. They were forgiving. They were accepting. And she found her peace there.

    Molly: I think my UCD does define me but it’s not all in a negative way. I just think that it’s always gonna be part of me. I just don’t think it should define who I am as a person. It just defines my path.

    Previously to RAVICTI, was a capsule, I took for the same purpose. It just was a lot more difficult because of the amount that I took.

Jocelyn

  • Read transcript

    I like to spend time with my family and friends. They bring out a lot of joy in me. And I also like to spend a lot of time with my dog. I have a French bulldog. Her name is Ceonna.

    I enjoy going on walks at the beach, walks at the park. I love the fresh air. I love nature. It really just makes me feel at home. It brings me peace.

    My name is Jocelyn. I was diagnosed with a UCD at the age of 8 years old.

    I know that living with a UCD is overall a roller coaster ride. I do have my ups and I have my downs. I have my good days and I have my bad days.

    I would wake up with an upset stomach. And I would just run to the restroom. There were certain things where I would eat and it would come right back up. There were times where I started missing school. We took many, many trips to different doctors, different hospitals. They would just say, “it’s a flu or it’s a stomach bug.” I didn’t know why I wasn’t able to eat certain things like my classmates.

    I remember when I was in middle school, when I was at the cafeteria line, everyone always had those same lunch. All my classmates on Fridays would eat pizza, and I couldn’t eat pizza. And I think I got to a point where I was very shy and I wouldn’t say much. I didn’t say, like, hey, guys, I have OTC and I can’t eat certain things. And it took me some time to get out of my little cocoon.

    I think once I was also comfortable with myself, like, hey, if I change the way that I eat and if I am on my medication the way that I’m supposed to be taking it, everything runs smoothly. Everything goes nicely and then everyone will understand my story a little bit more. So, I think once I was able to really be comfortable with myself in a way where I had to take my medication.

    I don’t think it ever separated me for anything, but it was a little bit challenging just to have a voice.

    A few tips and tricks that have helped me stay on RAVICTI have been just making sure that I keep the syringes somewhere where they’re visible.

    I love coffee. So, I would sometimes put my syringes next to my coffeemaker because I would grab my coffee and I need to make sure that I grab my syringes.

    I think I’m very blessed that I’m able to truly enjoy the beauty of life with RAVICTI. I’ve been able to truly enjoy all the foods that I want and also balance taking RAVICTI. I’m able to go hiking with my friends. I’m able to just enjoy either vacations or longer walks with my dogs.

    I wish I would have known more about RAVICTI when I was diagnosed at the age of 8. I think it has helped me so much along my journey now.

    I think there’s so many people in this world that have UCD or carry some kind of disorder that it doesn’t make us any different than anybody else. And it never stopped me. And I think that disorder should not stop you and it should only make you stronger.

    I think it’s, truly, just finding a voice and just speaking out loud making sure that everyone else understands it and the person that has UCD is one thousand percent comfortable.

Juli

  • Read transcript

    My name is Juli. I’m 46 years old. I live with my husband and my son and my new puppy, Jaime. And I live with OTC. Growing up, I did have a lot of different symptoms. Nausea. Terrible stomach pains a lot. My hair was very thin. My nails didn’t grow. I didn’t eat very much. I just wasn’t hungry during the day. People thought I had an eating disorder.

    When I did go to the doctor, they would run a gamut of tests and everything would come back normal. They’d pull my mom aside and say, “This is all in her head. This is something she’ll outgrow.” Even in my early 20’s, when I ended up in the emergency room for similar symptoms, they ran all the tests that they could and they couldn’t find anything. So the next step was to pull in a psychiatrist to ask me if I felt safe at home. Do you feel safe in your relationship? That was very hard. Because I knew something wasn’t right and nobody was listening to me.

    I was first diagnosed with OTC in 2011, I had just given birth to our third son, Eli. And he had passed away after a battle with OTC and two failed liver transplants. Our first son, Luke, is not affected at all, our second son, Noah, was also affected and he passed away at four days old.

    Shortly after Eli passed away, I was tested myself. I got a call from a genetic counselor. No one in my family had even heard about this, including myself.

    As a woman living with OTC, you know, you hear a couple terms. You hear carrier and you hear someone with OTC and, and to me, personally, those terms are interchangeable.

    There are lots of women that are told they’re just carriers of OTC and maybe they haven’t experienced any symptoms, or maybe their symptoms are so mild that they don’t recognize them as symptoms. If they feel like something is wrong, that they’re experiencing these, you know, talk to your doctor about it. You know your body more than anyone else. Just because you haven’t had symptoms in the past doesn’t mean you can’t start developing them.

    So, another thing is just really trust your body. Even if the doctors are telling you there’s nothing wrong with you, if you know something’s not right, just trust yourself. Keep advocating and fighting for yourself. Because you are the only one that truly knows you and knows what you feel like. So please, don’t stop fighting for you.

    Family is very important to me and I don’t want to miss a thing. So what I can do right now is protect myself the best of my ability. Staying on my medication, keeping with my low-protein diet, just trying to live the best fullest life I can so I can be present for my family, so I can be fully present for my son, so I can be there at all of his activities. So I can see him play in the band, so I can be there with my husband, go on trips, go for walks, and just be able to live my life.

Everyday life with RAVICTI and living with a UCD

Daily-Life Stories

Hilary and Myiah’s Daily Routine

  • Read transcript

    We have protein guidelines, and we take our RAVICTI regularly. We can enjoy our foods, but not have to worry or be stressed out. Of course, we only have protein mainly for one meal, whether it’s lunch or dinner, just to keep within the guidelines from the doctor, but we can still enjoy most things.

    We take it once in the morning when we wake up and I take a dose with me to work. Since I don’t need to mix it with anything, I can just take it.

    I have a pretty big support system. I have my mom. She’s very helpful to me. She helps to make sure that Myiah gets her RAVICTI every morning before she gets on the school bus. Myiah’s father is very supportive. He makes sure Myiah takes her medication every time she’s with him. I have my boyfriend. He’s been a big help with me, also. It’s very helpful to know you’re not alone when dealing with things like this.

    I really enjoy getting my hair done, doing my nails. I think it’s very important to focus on taking care of myself as an individual, so I can remind myself, I’m not just a mom taking care of people, paying bills. I think that’s really important, to take time for yourself and do things that you enjoy doing. I believe that it genuinely makes you a happier person, more relaxed person.

    So you can give your best version of yourself to everyone else. The people you love and care about.

    I always want to put my kids first, so I feel guilty any time I do things for myself, but you can’t do things for others, if you can’t take care of yourself. My kids are much happier when they know their mom is happy and taken care of, for sure.

Molly’s Daily Routine

  • Read transcript

    RAVICTI is incorporated in my daily life pretty simple. I try to prep my medications the night before. Now that doesn’t always happen, but it always happens in the morning before work. That’s just something I like to try to do just to be a little bit more prepared. But I take it at breakfast, lunch and dinner. So, I take it with all of my food. Like big meals.

    When I go out just for the day, these every, every day I pack my meds in advance. So, wherever I am, wherever I go, whether I’m going out with family or friends, I just, I have it with me in my pouch. Like pre-packed, packaged, all done.

    I think a lot of times when we go out, people don’t really have a chance to notice because I do it so quick, as I’ve done it for so long that it, a lot of people don’t even realize I’ve taken my RAVICTI. All the time. Even my mom and my grandma will be like, did, did you take it? And I’m like, I have already done that. (laughs) So, yeah.

    It doesn’t matter if you are with new friends. It doesn’t matter if you’re on a date. Like, having to get over the fear of what other people think is going to be your best friend, and not worrying because once you start limiting yourself, you’re not gonna be able to take care of yourself. And I think that’s so important.

Jocelyn’s Support System

  • Read transcript

    Ever since I was diagnosed at the age of 8, I’ve had really great support systems on my side.

    I’ve been very blessed to have my friends, my family, my mom, who is probably my right hand, my everything. Not because she’s a carrier of OTC, but because she has been by my side through thick and thin. Whether it’s been the hospital visits, whether it’s been just really understanding what OTC is having to do, a family tree breaking down of where it started, how does it get passed down, if it get passed down, just truly knowing more.

    But having my mom as my right hand support system I think has made everything and throughout this OTC journey so much easier.

    I have had an amazing group of girlfriends that have been able to support me throughout my entire journey. I’ve had pretty much the same group of girlfriends ever since high school.

    It took me also just a little bit to truly just sit down with them and have them really understand what I have.

    The fact that my friends really made me so much comfortable, it made everything so much easier. Just having their support has really just made a big impact in my life.

    But they’re always very attentive as to well, what can Jocelyn eat or what can’t she eat? Can she eat something from the menu? Will she be OK? Does she have her medication?

    Those friends turned into family because they cared so much about me and it just made my life so much easier.

    I have to thank the Horizon by Your Side team. They have been really by my side, and I think one of my biggest persons also is my PAL.

    I think just having somebody that understands the UCD and just having someone that truly just knows what you go through is so much easier. And also just having someone available at all times if you just have a question.

    I have a French bulldog, her name is Siona, and she’s pretty much taking over a little bit of my life. She has genuinely helped me also throughout this entire process. Having a dog in my life has made such a big impact but it’s not always easy. So I think it’s nice to have people in my life and such a beautiful pet that I really love.

    I think my biggest motivator to stay on track with living with a UCD is the beauty of life.

    I love that I can just keep going. I think the number of times that I’ve been hospitalized has not stopped me, nor will it stop me.

    I’m very lucky to be able to have amazing people in my life and just really, just keep pushing forward in the things that I love.

Molly’s Take on Dating and Relationships

  • Read transcript

    Dating with a UCD has been very similar to having friends who also know about my UCD. Just because I, right outset, tell people, because a lot of times, we do the first time is go and eat, or go and have a drink. It’s just a very socially normal thing to go and do. And I feel like if I’m trying to hide part of it, it, it just doesn’t make sense to hide anything. I will, I’m not afraid to talk about it. So, if people want to know, that’s fine.

    I find that in relationships and friendships or dating or personal life, I haven’t really had anybody absolutely opposed. Because, frankly, I don’t think anybody should oppose a disorder. That just seems wrong. So, I, thankfully, at least, haven’t experienced that.

    I think that having to feel like I looked different was more something to cope with, and growing up didn’t really start feeling different until gymnastics. It was when I started gymnastics and I had a feeding tube and my leo went over my feeding tube and my feeding tube stuck out. It was more, okay, now I look different. And that was something that I really struggled with. And I’m glad I was able to get over that because I continued doing gymnastics up until senior year of high school and competed and traveled.

    My boyfriend, Grant, has been so supportive in terms of being able to take care of me when I’m sick, specifically… He has my back. And he’s been there for every single hospitalization and all of those, which has been really nice to have like another support person in my life that cares enough to continue to show up.

    Grant makes me feel very safe. I think it’s just his personality and, like, knowing that he’s been by my side for so long that I don’t think—It’s just kind of almost like a loyalty thing. Like, I know that he’s here for me.

Advocating for UCD care

Advocacy

Teaching Myiah to manage her condition

  • Read transcript

    Myiah, being 10 years old, she doesn’t fully understand what having a UCD means or entails. At this point, I think that she’s kind of more annoyed with it. She has to take a medicine. She has to go to the hospital. She has to get blood taken. You know, things that other kids her age don’t have to do. She’ll say, Mom, why do we have to do that? Mom, why do we have to do this?

    I’m teaching her the importance of it. It’s important to be able to take care of yourself. Watch your diet, take your medicine, go to the doctors, because these are the things that you need to do to make sure that you stay healthy. You’re healthy because you do these things and you need to continue to do these things.

    Myiah is becoming responsible and taking care of herself at 10 years old. I am teaching her the importance of making her doctor’s appointments and sticking to her doctor’s appointment and how it’s important to take her medication when she’s supposed to take it, and to watch her protein intake. She still asks me all the time, like, Mom, is this too much protein? She’s not really sure of exact amounts but she knows like, hey, I already ate a piece of chicken today. I probably shouldn’t eat a whole steak tonight.

    Myiah is getting more comfortable at getting her own medication. She knows her dose and she is fully capable in getting it. So often times in the evening, before bedtime, Miah will get her own medicine and bring it to me and I will tell her, ‘Hey, it’s time for your medicine’. I just check it and make sure that it’s the appropriate dose before she takes it. But she’s doing well on her own, learning. And it’s a simple process once you just get into a routine. And it’s basically just teaching her that it’s not a chore. It’s just one little step that you add to your day and it’s not a big deal.

    It’s hard, because you know, as your kids get older, you have to relieve yourself of those duties eventually. And so, I’m trying to prepare myself and I’m trying to prepare her the best that I can to have her help to administer her medication and to know the importance behind it so she can make it as much of a routine and normal as she possibly can now.

Advocating for your child

  • Read transcript

    Amy:

    It took me a few times, but now I’m that hospital mom momma bear. …After the lab techs come up, and they poke her twice…I’m the mom that’s not afraid to ask for the anesthesiologist because…if they waste 6 different poke sites, just trying to start one IV, we’re gonna be in trouble for that whole hospitalization.

    And I had had different experiences with doctors and hospitals, so I knew right away that if you walk in and you act like you own the meeting, you own the meeting. And that’s what I did.

    You have to be aware of what’s going on. And you know your child best.

    David:

    Thank God for doctors.

    …They’re trying to do their best to serve you… So you have to treat them well. But at the same time you have to be an advocate when you present to a, ah, an emergency room or a medical situation with your child.

    You won't get it from yelling. Don’t do anything like that. Just persistently be an advocate for your child.

    You have to do it as a parent, and we’ve been teaching our son, to be his own advocate.

    Do it sternly, firmly, consistently. Do not back down. If you do not get results, find somewhere where you can.
